Economic Actors & Reward Mechanics
Hubic’s decentralized economy is structured around three primary roles, each contributing to the zk-compute pipeline and earning HUB based on verified outputs:
👤 1. Model Owners
Role: Register zk-compatible AI models to the on-chain registry. They define pricing and receive a share of all inference fees generated by their models.
💸 Revenue Model:
Set a flat or dynamic price per inference call.
Earn a default 60% share of every valid task using their model.
Can tokenize model ownership as ERC-20/NFT to distribute income.
🌍 RWA Integration:
Tokenized ownership: Revenue is streamed to token holders.
DAO-managed models: Governance over fee structure, model updates, and upgrade rights.
⚙️ 2. Executors (zk-Inference Nodes)
Role: Run the model’s zk-circuit off-chain and generate a proof.
🧾 Participation Requirements:
Stake HUB to enter execution pools.
Meet proof latency and compactness constraints.
💰 Compensation:
Earn 20% of inference fee per job.
Bonus tiers for proof efficiency, model diversity, and low error rates.
📈 Enhancements:
Performance history boosts future routing priority.
zk-signed benchmarks can be published for discoverability.
✅ 3. Verifiers (Validation Nodes / Contracts)
Role: Confirm the integrity of each proof and enforce correctness.
🔍 Responsibilities:
Load model hash and verification key from the registry.
Match proof → input → model → output.
Trigger payment or slashing.
💰 Rewards:
Receive 20% of inference fee per successful verification.
Long-term bonuses based on uptime and audit performance.
⚠️ Slashing Conditions:
Accepting invalid proof
Slashing of staked HUB
Collusion with executor
Slash + blacklisting
Missed validation SLA
Loss of role + reward cut
⚖️ Revenue Split Summary (Per Inference Job):
Model Owner
60%
HUB
Can be auto-routed to RWA holders
Executor Node
20%
HUB
zk-proof generation
Verifier Node
20%
HUB
On-chain proof validation
This system ensures that all compute work, validation, and model ownership is financially accountable, proof-enforced, and natively composable with RWA tokens and Ethereum protocols.
